Product Overview


RENT AMPLIFIER RESEARCH 900S1G4 (Call for Availability)

The Amplifier Research 900S1G4 is a portable, self-contained, air-cooled, broadband, completely solid-state ampifier designed for applications that require instantaneous bandwidth, high gain and linearity. The highly versatile 900S1G4 amplifier consists of three 350S1G4 sub-amplifiers housed in a single equipment rack with a controller. The 900S1G4 can function as one amplifier or be separated and operate as three separate 350S1G4A amplifiers which can be used independently. 

Features and Specifications of the Amplifier Research 900S1G4 Amplifier include:

  • Features:
    • Provides a minimum of 900 watts of RF power when used with a sweep generator
    • Digital Control Panel (DCP):
